Title: Improvements in and relating to the manufacture of railway sleepers and the like
IPC: B28B1/52
Filed: 1947-11-15
Abstract: Railway sleepers and the like are manufactured by superimposing layers of fibrocement in the wet state with interposed metal reinforcements and compressing the layers, the sleepers being pressed one at a time and the pressure applied being greater than that required to compress the layers to the required thickness of the finished sleeper, such pressure being applied only momentarily.  The pressure is such that when it is relieved, the sleeper expands to the required thickness.  The mould forms part of the press, and the sleeper is removed from the mould immediately after compression.  A pressure somewhat above 550 kgs. per sq. cm. is used.

Abstract: 1478208 Automatic control of speed RENGO KK and NIPPON RIRAIANSU KK 23 July 1975 [29 Oct 1974] 30900/75 Heading G3R In a rotary cutter control system for cutting a continuously fed web into desired lengths, an actual web speed signal is multiplied by a coefficient equal to pre-set values of the cutter circumference and the desired length. The cutter speed is controlled according to the combination of the multiplier output and the difference between this output and the actual cutter speed. As shown, in Fig. 3, the desired length L of the web e.g. cardboard and the circumference I are set digitally at a and b, their quotient K being derived by circuit c upon completion of cutting as sensed by device OP. The actual web speed signal from tachogenerator PG A  is phase shifted, multiplied at d by K to form a signal K# A  which is compared in a digital-analogue converter M with the phase shifted actual cutter speed signal from tachogenerator PG B . The result of the comparison is combined by adder n with the signal K# A , from multiplier d via frequency to voltage converter k, to form the speed control signal V o  for a motor driving the rotary cutter. The outputs of tachogenerators PG A  and PG B  are said to be pulse signals.

A method of reducing the diameter of work in a turning operation comprises traversing the work by two cutting tools which are moved in unison towards and past one another and in which the depth of cut of the two tools is also increased in unison as their cuts in the work merge. A workpiece 4, Fig. 2, having a high length/diameter ratio is supported between a headstock 2 and tailstock 3. Two saddles 5, 6 with transversely adjustable tool carriers 9, 10 are provided at the front and back of the lathe respectively. The saddles are traversed by screws 7, 8, and are moved in unison in opposite directions. The tools 11, 12 are set initially to give the same depth of cut and when the cuts merge the tools are automatically moved to increase the cut and continue past one another to the respective ends of the work; the second cuts may be finishing ones. Automatic control of the cut is provided by vertical shafts 16, 17, Fig. 3, carried by the respective saddles and provided with pinions 18, 19 engaging racks 13, 14 connected to the tool slides. The shafts are rotated by similar rack- and-pinion gearing at their lower ends, but the racks in this case are moved by hydraulic motors 22, 23, of known type which " followup" the movements of tracers 25, 26, sliding along a pattern 24. Abrupt shoulders may be turned on the work where profiled work is required.

Abstract: To minimise its tendency to permanent soiling, a pile fabric, in which more than 20 per cent of the pile yarns are of vegetable or artificial fibres, is treated upon the outer or exposed portions of the pile with a dilute aqueous colloidal solution of inorganic substances containing a major proportion of silica to form a coating of a weight in solids from about 0.15 oz. to about 0.50 oz. per square yard of pile surface, the fabric then being dried.  The pile may be of wool or mohair blended with yarns of cotton, jute, ramie, viscose or acetate rayon, nylon or polyvinylidene chloride, or the pile may comprise entirely yarns of artificial or vegetable fibres. The treating solution may be made from a commercial product, Atta Clay, comprising a complex hydrated aluminium magnesium silicate containing about 67 per cent of silica and may also comprise a small proportion of carbon black or other coloured inorganic substances to avoid lightening the colour of a dyed pile fabric.  It may be included in a foaming detergent composition.
